Baby-specific soundtracks, that are dramatically different to lullabies, combine layers low-pitch, everyday domestic noises and physiological sounds that mimic the womb. The Sounds for Silence package includes a book with practical information on health and settling issues, with reliable expert information and is all parents need to know before they start to panic. Sounds for Silence has been developed by Dr Zehnwirth using over 20 years of specialist Paediatric experience.
